APC NetShelter SX AR3155SP 45U 750 mm Wide 1070 mm Deep | Rack Enclosure

Keep critical infrastructure organized in a rack enclosure designed for high-density deployment. The APC NetShelter SX AR3155SP provides 45U of mounting space in a 750 mm-wide frame with 1,070 mm depth, giving you the clearance needed for deeper servers, cable routing, and front-to-back airflow planning. That extra depth matters when you are standardizing mixed hardware across multiple rows or building out a new cabinet strategy for enterprise workloads. This enclosure is a strong fit for teams that need more than a basic rack. The wider footprint helps simplify cable management and accessory placement, while the tall 45U format supports efficient use of floor space in colocation rooms, server closets, and enterprise data centers. It is the kind of rack you choose when equipment density, serviceability, and long-term layout discipline matter. For procurement teams, the value is in the fit and finish: a purpose-built enclosure that supports structured deployment instead of improvised stacking or under-sized frames. For operations teams, it helps keep equipment accessible, organized, and easier to service over time.
